Offshore Wind in the UK

The UK has the world's largest installed offshore wind capacity, with the North Sea, Irish Sea and English Channel all hosting major projects.

Onshore Wind in the UK

Scotland leads UK onshore wind, but a planning moratorium in England (now lifted) suppressed growth in the south for a decade. New projects are now coming forward across all four nations.

UK Wind Energy Timeline

From the first turbine to world-leading offshore capacity — a history of UK wind power.

1991

Vindeby — World's First Offshore Wind Farm

Though built in Denmark, the concept inspired UK planners. The UK's first offshore project, Scroby Sands, followed in 2004 off Great Yarmouth.

1991

Delabole — UK's First Commercial Wind Farm

Cornwall's Delabole became the UK's first commercial onshore wind farm with 10 turbines at 400 kW each — a total of 4 MW.

2004

Scroby Sands — UK's First Offshore Wind Farm

30 turbines, 60 MW, off the coast of Great Yarmouth. Owned by E.ON, it demonstrated offshore viability and paved the way for Round 2 developments.

2010

Thanet Offshore Wind Farm

100 Vestas V90 turbines, 300 MW — then the largest offshore wind farm in the world, located off the Kent coast in the Thames Estuary outer area.

2013

London Array — Beating World Records Again

630 MW, 175 turbines in the outer Thames Estuary. Retained the world's largest title until 2017, operated by a consortium including Ørsted, E.ON and Masdar.

2019

Hornsea One — First 1 GW+ Offshore Wind Farm

1,218 MW from 174 Siemens Gamesa 7 MW turbines in the North Sea. Enough to power over 1 million UK homes, built by Ørsted 120 km from the Yorkshire coast.

2022

Hornsea Two — 1.3 GW Sets New World Record

165 Siemens Gamesa 8 MW turbines for 1,320 MW total. Again built by Ørsted, adjacent to Hornsea One. Powers 1.4 million homes.

2024

Dogger Bank — World's Largest Under Construction

3,600 MW across three phases (A, B, C) using GE Haliade-X 13 MW turbines. Operated by a consortium of SSE, Equinor and Vårgrønn. Phase A expected 2025.

2030

Government Target: 50 GW Offshore Wind

UK government committed to 50 GW offshore by 2030. Projects in the pipeline include Hornsea Three & Four, East Anglia Three, Morgan & Mona, and floating offshore wind in Scotland.

Wind Turbine Technology

Modern wind turbines are engineering marvels. Here's how the technology has evolved and where it's heading.

Offshore Turbine Sizes

  • 2010s: 3–5 MW (Siemens SWT-3.6, Vestas V112)
  • 2018–22: 8–10 MW (SG 8.0-167 DD, GE Haliade-X 12MW)
  • Now: 13–15 MW (GE Haliade-X 13MW, SG 14-222 DD)
  • Upcoming: 20+ MW class turbines in development
  • Rotor diameter now exceeds 220m on largest models

Foundation Types

  • Monopile: Most common, suits depth to ~45m
  • Jacket: Four-legged, deeper water and softer seabeds
  • Gravity base: Large concrete base, less common
  • Floating: Spar, semi-submersible, TLP — for 60m+ depth
  • UK floating pilots: Kincardine (50 MW, world first at scale)

Grid Connection

  • Offshore substations step up to 132–220 kV AC
  • HVDC export cables for projects beyond ~100km
  • Offshore transmission owners (OFTOs) run cables to shore
  • Offshore Wind Acceleration Programme addressing delays
  • Eastern Green Link 1 & 2: HVDC links Scotland–England

Floating Offshore Wind (FLOW)

  • Scotland's deep waters ideal for FLOW development
  • ScotWind allocated 25 GW of seabed including 15 GW FLOW
  • INTOG: Innovation & Targeted Oil & Gas — 5 GW near-shore
  • Hywind Scotland: 5 turbines × 6 MW = 30 MW, Equinor
  • Kincardine: 5 × 9.5 MW Vestas — world's largest FLOW farm
